The lottery machine 51d in FIG. 9 has a slot type lottery mechanism, and a winning combination is obtained when a predetermined number is obtained. In the chance game as the lottery game, for example, a lottery using the lottery machine 51a is executed as the first lottery. When winning, the lottery using the lottery machine 51b is executed as the second lottery. When winning, the lottery using the lottery machine 51c is executed as the third lottery. When the third lottery is won, the player can obtain a jackpot. On the other hand, if the game is not won, the chance game ends, the medals are paid out according to the lottery result, and the normal game returns. The lottery machines used in the chance game three-time lottery are specified in advance, but can be changed by satisfying predetermined change conditions. The change condition will be described later.

  As the initial setting, the winning probability of the three lottery machines performed in the chance game is 1/2 in the first lottery machine 51a, 1/5 in the next lottery machine 51b, and the final lottery machine 51c. The winning probability is set to 1/10, and each expected value when 100 medals are put is set to 100. When winning at each lottery machine 51, the player wins 100 medals at the first lottery machine 51a, and 200 medals at the first lottery machine 51b, and 200 medals earned at the first lottery at the second lottery machine 51b. In the third lottery machine 51c, 10,000 medals can be paid out with 1000 medals acquired in the second lottery as a bet. As described above, the winning probabilities of the lottery machines 51a to 51c are different, and the payout amount is also different according to the winning probability. The lower the winning probability, the higher the dividend. In this embodiment, the expected value is set to 100 for 100 medals to be multiplied in one lottery by the lottery machine. In addition, various mini-game lottery machines such as bingo-type lottery machines and card game type lottery machines such as poker are provided, and different lottery probabilities are set.

  FIG. 10 is a flowchart showing a chance game control process routine executed by the control unit 40. The chance game control process routine is a process for controlling the progress of the chance game executed on the condition that the boss character ECB is defeated in the bonus game and the chance game button 16 is pressed. The control unit 40 executes the first lottery using the lottery machine 51a (step S1). The lottery is performed with the lottery probability set in the lottery machine 51a. A random number is used for the lottery. The control unit 40 determines whether or not the first lottery has been won (step S2). When winning, the control unit 40 pays out a payout (step S3), and executes the second lottery using the lottery machine 51b (step S4). In the second lottery, the first payout is played as a premium. The control unit 40 determines whether or not the second lottery has been won (step S5), and if it has been won, pays out a payout (step S6). The control unit 40 executes the third lottery by using the payout paid out in the second lottery as a premium (step S7). The control unit 40 determines whether or not the third lottery has been won (step S8). When the control unit 40 wins in the third lottery, the control unit 40 pays out a jackpot together with a predetermined effect (step S9). This processing is terminated. On the other hand, if the lottery is lost in each lot, the control unit 40 executes a process according to the lottery result (step S10) and ends the current process. Depending on the lottery result, a small amount of payout, items that can be used in the game, and the like are awarded to the player.

  In the above-described process, in the chance game, a maximum of three lotteries are executed by the lottery machines 51a to 51c (steps S1, S4, and S7), and a jackpot can be obtained when the third lottery is won (step S9). Steps S1, S4, and S7 executed by the game control unit 42 of the control unit 40 function as lottery execution means.

  FIG. 11 is a flowchart showing a lottery machine change processing routine executed by the control unit 40. The lottery machine change processing routine is a process for changing the lottery machine used in the chance game. As a change condition, it is set to be lost in a chance game lottery. First, the control unit 40 determines whether or not the player has won the first lottery by the lottery machine 51a in the chance game (step S11). When winning, the control unit 40 gives a payout to the player (step S12). Then, the control unit 40 executes the second lottery by the lottery machine 51b by using the payout given to the player as a bet, and determines whether or not it has been won (step S13). When winning, the control unit 40 gives a payout to the player (step S14). The control unit 40 executes the third lottery by the lottery machine 51c using the payout awarded to the player as a bet, and determines whether or not it has been won (step S15). When winning, a jackpot is awarded to the player (step S16).

  On the other hand, when a lottery is selected in any of the steps S11, S13, or S15, the control unit 40 performs a process according to the lottery result (step S17). Depending on the lottery result, a small amount of payout, items that can be used in the game, and the like are awarded to the player. Then, the control unit 40 permits the change of the lottery machine that has been lost by the player (step S18). When the player loses in the first lottery, the player can change the lottery machine 51a used in the first lottery. The control unit 40 receives a change from the player (step S19). When the player inputs an instruction to change to the lottery machine 51d to the touch panel 14, the control unit 40 changes the lottery machine used for the first lottery from the lottery machine 51a to the lottery machine 51d (step S20). The changed lottery machine 51d is also applied to other players who play on the game machine 1, and unless changed again, the player who plays the next chance game draws the lottery machine 51d in the first lottery. Will do. By changing the lottery machine, the preference of the player is reflected. For example, only lottery machines that are easy to win but have low dividends are set, or conversely, lottery machines with high payouts are set. To do. Even a player who cannot participate in the chance game can change the setting of the chance game, so that other players can win or lose with the lottery machine set by the player.

  According to the above-described process, when the player loses the chance game (steps S11, S13, and S15), the process according to the lottery result (step S17) is performed, and then the selected lottery machine can be changed ( Step S18). The player selects a lottery machine to be set (step S19), and the lottery machine is changed (step S20). The lottery machine changed here is applied as a setting of the entire game machine 1, and when another player plays the chance game, the lottery machine is played with the changed lottery machine. In the chance game, the game reflects the preference of the player who plays the game machine 1. The player also aims to play with a lottery machine set by the player. On the other hand, it is also possible to intentionally set a lottery machine that interferes with the chance game of other players. Therefore, the game characteristics of the game machine 1 are diversified, and the interest of the game can be enhanced. In the above-described process, the processes in steps S11, S13, and S15 executed by the lottery machine management unit 43 of the control unit 40 function as a lottery execution unit, and the processes in steps S18 to S20 function as a lottery mechanism change unit. Three lottery machines selected in the chance game correspond to the selection lottery mechanism.

The present invention is not limited to the above-described form and can be implemented in various forms. For example, in this embodiment, the change condition is set to be a lottery by chance game lottery, but is not limited to this. For example, in a slot lottery or a roulette lottery performed in a normal game, a lottery machine change right may be provided as a lottery option, and acquisition of this change right may be set as a change condition. A first modification will be described below. Also in the first modified example, except that a change right option is provided by lottery machine change processing and various types of lotteries executed in the base game, the description is omitted. Figure 1 2 is a flowchart showing a lottery machine change processing routine control unit 40 of the game machine 1 according to a first modification of this invention. First, the control unit 40 executes a roulette lottery of a normal game (step S31). As an example, a roulette lottery performed in a normal game will be described. This roulette lottery is executed when the ball B falls into a predetermined hole of the gate GT shown in the game screen GS of FIG. Alternatively, it may be executed when a predetermined game condition is satisfied, such as when a predetermined enemy character EC is defeated. In the roulette lottery, options such as paying out medals and giving items are set. At least one of the options is set as a change right of the lottery machine as a change option.

The control unit 40 executes the roulette lottery and determines whether or not the lottery result is the grant of the right to change (step S32). When the lottery result of the roulette lottery is granting the right to change, the control unit 40 permits the player to change the lottery machine (step S33), and ends the current process. After the roulette lottery, the change right acquired by the player may be notified to the other player that the lottery machine will be changed on the common display device 4, and the selection of the lottery machine may be displayed. At the time of execution, a player who has the right to change may be asked whether or not to change the lottery machine. The acquired change right is stored in the play data 45, and the player may use the change right at an arbitrary timing. On the other hand, if the drawing result in Step S 3 2 was choice but change the rights, the control unit 40 executes a process corresponding to the lottery result (step S34), and terminates the current process.

In the above-described process, when a lottery machine change right option is won in any lottery game executed on the game machine 1 (step S32), the winning player is permitted to change the lottery machine (step S33). Since the roulette lottery performed in the normal game is executed more often than the chance game, the player can easily obtain an opportunity to change the lottery machine of the chance game. Even if you change to your favorite lottery machine, there is a possibility that other players will change before playing the chance game, so there will be a bargaining with other players, and there will be tension in the game. It is also motivated to play a chance game while it is set as a favorite lottery machine, and the interest of the game can be enhanced. In the first modification, the process of step S31 executed by the game control unit 42 of the control unit 40 functions as an option lottery means, and the process of step S33 executed by the lottery machine management unit 43 functions as a lottery mechanism changing means. .

In addition, the change of the lottery machine may be determined by voting in which all players playing on the game machine 1 can participate. A voting event is held, and the lottery machine to be changed and the lottery machine to be changed are determined by the majority of the players. Below, a 2nd modification is demonstrated. Also in the second modified example, since the lottery machine changing process and the voting event are held, the description is omitted because it is the same as the above-described embodiment. Figure 1 3 is a flowchart showing a lottery machine change processing routine control unit 40 of the game machine 1 according to a second modification of this invention. First, the control unit 40 determines whether or not an event generation condition as a voting condition for holding a voting event is satisfied (step S41). As an event generation condition, for example, it is set that the number of times that the game machine 1 has challenged a chance game and failed to acquire a jackpot has reached a total of 10 times. The jackpot can be acquired by winning in the third lottery, but in addition to the loss in the third lottery, the first or second loss is counted as the number of failures.

  If the event occurrence condition is satisfied, the control unit 40 holds a voting event (step S42). In the voting event, a notification of the voting event is displayed on the monitor 13 of each station unit 2, and a plurality of combinations of the lottery machine to be changed and the lottery machine after the change are presented. As the lottery machine to be changed, at least one of the lottery machines used for each lottery is designated. The control unit 40 receives a vote from the player (step S43). The control unit 40 receives a vote for a predetermined period, and after the period has elapsed, the vote is closed and presents a vote result (step S44). Then, the control unit 40 changes the setting to a combination lottery machine with a large number of votes (step S45), and ends the current process. For example, when the combination of “change the third lottery machine to the lottery machine 51d” has the largest number of votes, the third lottery machine is changed to the lottery machine 51d. All players who play on the game machine 1 can participate in the voting event, and the combination with the highest number of votes is set as the lottery machine. A sense of unity can be formed between players playing on the game machine 1, and the game can be excited.

  In the above-described processing, the event occurrence condition functions as a change condition, and when a voting event occurs (step S42), the lottery machine combination with the largest number of votes is changed (step S45). The processes of steps S41 to S44 executed by the game control unit 42 of the control unit 40 function as voting execution means, and the process of step S45 functions as a lottery mechanism changing means. Note that the lottery machine determined at the voting event is not limited to the lottery machine with the largest number of votes, and may be changed to a lottery machine with the smallest number of votes, for example. You may make it change into the lottery machine of the predetermined number of votes obtained in advance. A bargaining event occurs between players, and the voting event can be enlivened.

  In the above-described embodiment, the lottery is performed three times by the lottery machine as the chance game, but is not limited to this. For example, one lottery may be performed. The lottery machine used for one lottery can be changed in a form including the above-described modification.
